This invention relates to a device particularly adapted for sharpening scissors. It is the object of my invention toprovide an improved form of scissors sharpener; one that is relatively simple and hence cheap to manufacture, but onelthat is highly eflicient in operation.

My invention will be readily understood by ref erence to the annexed drawing, wherein:

Figure 1 is a substantially full-size view of a preferred form of my invention.

Figure 2 is a view similar to, Figure 1, but with the device turned 180 degrees, and showing the ends of the scissors blades in positionon the sharpener.

Figure 3 is a view on a reduced scale o1 the'device shown in Figure 1 turned to the left at an angle of 90 degrees, and with a pair of scissors in position to start the sharpening operation.

In the drawing, the sharpening device includes a handle 1 of any suitable material, such as wood, having a central bore 2, in the upper end of which is positioned a metallic collar 3 having a through which pass the arms 6 and '7 of a guide and support member 8. It is to be understood that the material of the handle under the ferrule, where the arms 6 and 7 pass through is cut away or recessed to provide space for the arms 6 and steel and the outer surface provided with a large a number of flutes as in many forms of steels used in table carving sets. The sharpening member or steel 11 is adapted'to fit into the collar 3 and into the counterbore 2 and can be adjusted longitudinally of the handle and fastened in position by the set screw 4. Theguide and support member 8 has two specially formed surfaces 12 and 13 which are arranged in offset relationship, one to the other, as shown in the variousviews.

However, it is to be noted that the oifset 14, on

one edge, is preferably somewhat greater than the offset 15 on the opposite edge, so' that-the two surfaces 12-and 13 are not in the same parallel planes, but the lines of the oifsets 1a and 15 are substantially on the axial center of the sharpening member or steel 11.

This arrangement is so that when the blades 16 and 17-of the shears are placed againstctheirie spective surfaces 12 and 13, and straddling the sharpening member 'll about as indicated in Figure-3," the"cutting edges-18 and 19 of fthezblade's,

' which are 'at'a' sharp angle 'withrespectto .the O,

blades, will be brought into proper engagement with the sharpeningmember 1'1 asis clearly indie dated in Figure'2. Q 1 In sharpening the scissors, the device is held by the handle, for example in the left hand, with 65; v the devicepreferably turned 90 degrees to the right from the position shown in Figure 1, and then the scissors are placed. on the guide and,

support member 8 about as shown in Figure 3."

The scissors are then, operated just as though a 79 cutting operation were to be performed with a slight drawback on the hand. This causes the cutting edges 18 and 19 of the blades to pass lengthwise across the serrations. or flutes on the sharpener 11, thereby sharpening the cuttingflli,

edges 18 and 19.

' It has already, been pointedout that the steel 11 may be adjusted longitudinally or rotated in the handleso that new surfaces maybe readily brought into position, to be engaged by the scissors 8Q,

blades, and from the construction ofthe guide and support memberv 8, as has been described, the cutting edges 18 and. 19 0f thescissors blades will be brought, at the correct angla'against the steel 11, without the exercise of any greatamount of 8 5, attention on the part of the operator who has only to. see that'the blades 16.and l7 are placed against the surfaces 12 and 13 in the manner set forth.

Certain changes in without departing from the'spirit of the invention. For example, the fine serrations or flutes on the sharpenerll may be arranged in a spiral manner, and the ferrule 5 may be thick enough or so; constructed as'to be directlytappedforai the set screw -4', thereby entirely doingaway with the collar 3.. V a

Having thus describedmy invention, whatI I Claim is: l

1. A scissors sharpener including a handle, a .190

guide and support member carried by the handle, said member having two laterally offsets'urfaces with a hole passing'through'parts of bothsurfaces at the offset, and a sharpening member ex tending fromthe handle through said hole.

2. A scissors sharpener including a handle, a guide and support member carried by the handle, said member having two laterally offset surfaces positioned in different planes lying at an angle 'to the axis of the'handle, said guideand support HQ detailsmay also be made 99;

member adjustably carried by'the handle and extending through said hole.

3. A scissors sharpener as set forth in claim 2, further characterized in that the said different planes are not parallel.

4. A scissors sharpener including a handle, a guide ands'upport member having arms extending into and fastened to one end of the handle,said guide and support 'member having surfaces disposed at an angle to the axis of the handle and located in different planes at a slight angle toeach other, and a sharpening member adjustably device which extends through and beyond said surfaces at the offset.

carried by the handle and extending through said guide and support member at the junction-of said surfaces and in operative relation to said sur faces, whereby when the scissors blades are placed on said surfaces on opposite sides of said sharpening member, the cutting surfaces of the blades 'lying in -planes. making an angle other than a right angle with the axis of the handle, and a sharpening member passing throughfsaid guide and support member at the junction of said surfaces and carried in adjustable relation with said surfaces, whereby when the scissors blades are placed on said surfaces on opposite sides of said sharpening member, the cutting surfacesof the blades will make the proper angular contact with a surfaces and positioned so the plane of the offset substantially includes the axis of the sharpening 7. In a device of the class described, a handle, a circular sharpening member adjustably and removably carried by the handle, a' guide and supber,thereby forming two surfaces disposed in dif ferent planes at an angle to the axis of the sharpening member to receive the blades of the scissors GEORGE H.
